CAR-WHEEL.

, SI-EOIFIOATION forming part of Letters Patent No. 702,644, dated June17, 1902.

Application filed January 31, 1902. Serial No. 91,988. (No model.)

T0 at whom it may concern:

Be it known that I, MAX P. GERBING, a citizen of the United States,residing at Wentworth, in the county of Newton and State of Missouri,have invented certain new and useful Improvements in Car Wheels andTrucks, of which the following is a specification.

This invention relates to improvements in railway-car wheels and trucks;and the object of my invention is the provision of a simple form oftruck which has j ournaled therein an axle carrying car-wheels which areso constructed as to prevent the track from wear-' ing round upon itsinner edges or corner of the rail, and consequently lessen the wear andtearupon the flange of the car-wheel.

To attain the desiredobjects, my invention consists of a truck andcar-wheel embodying novel features of construction and combination ofparts, substantially asdisclosed herein.

In the accompanying drawings, Figure 1 is a side elevation of mycar-truck with the wheels in position therein. Fig. 2 is an end viewthereof. Fig. 3 is a sectional view of two railway-tracks with two of mywheels in position thereon, one of said wheels being shown in sections.Figs. 4., 5, and '6 are detail sections of the upper or peripheral edgesof car-wheels with my invention shown in modification.

Referring to the drawings,the numeral 1 designates the lower cross-barof the truck, to which is bolted the plate 2, which is connected to theupper plate 3 by means of the bolt 4, so that the springs 5, which areconnected, respectively, to the plates 2 and 3, will produce a cushionedeflect for the truck. Connected to the plates 3 are thetwodownwardly-inclined arms 6, whoseends are also connected to theupwardly-inclined arms 7 by means of the bolts 8, which also connect thelower cross-bar 1, so that the journal-boxes9 are supportedtherebetween. Connected to the truck by means of the lever 10 is avertical strip 11.

Mounted in the journal-boxes 9 are the reduced ends 12 of the car-axles13, said axles being provided with the annular ring or' on the wheel,and thus, with the key, assures a rigid structure. with the planeperiphery 18 and the peripheral flange 19, a groove 20 being provided atthe junction of the flange and plane 18 and may be of any desiredshapesuch, for instance, as shown in'Fig. 3, where it extends under theflange, so that its center is in direct alinement with the inner sideofthe flange and is substantially square in cross-section. In Fig. 4: Ihave shown the groove formed at the meeting edge of the flange andplane,its inner side being in direct alinement with the inner side ofthe flange. In Fig. 5 I have shown the groove as formed in the flange 19and having its lower edge in direct alinement with the plane 18 of thewheel. In Fig. 6 the groove is substantially circular in cross-sectionand is provided so as to be depressed below the junction of the plane 18and the flange19. It will also be noted that the inner edge 21 ofthe-flange 19 is roundedin order The wheel is provided that less wear onthe inside of the rail is also guaranteed.

From the foregoing description it is evident that I provide a car-truckof comparatively simple construction and wheels to be journaledvtherein, which are provided with a means to prevent the tearing orflattening of the inner edge of the track-rails, said means beingreadily provided in the wheels when the same are cast and which will addcomparatively little expense in such addition.

What I claim as new, and desire to secure by Letters Patent, is

1. A railway-car wheel provided with an annular groove at the junctionof its flange and,

plane, and a central opening having its outer mouth flaring. I

2. A railway-car wheel, comprising the contral hub having an axleopening therethrough with a flaring outer mouth and a recess the fulllength of theopening, a periphery integral with the hub and aflangeextendingbeyond said periphery,said periphery and flange being providedwith an annular groove at IOO.
